Title: Method and apparatus for positioning and expanding tubes in tube plates
IPC: B21D41/02
Filed: 1979-08-03
Abstract: Three elastic members 12, 11, 5 are placed in a tube 2 to be inserted into a tube-receiving bore in the tube plate 1. A rod 6 is pulled to axially press the first elastic member 12 so that the same is expanded radially outwardly into frictional engagement with the inner surface of the tube. The rod 6 is further pulled to axially move the tube by means of the frictional engagement between the first elastic member 12 and the tube. This movement occurs as the second elastic member 11 is axially contracted and is stopped when the tube-end engages a tube positioning sleeve 10 and bushes 15, 16 pressurising the member 11 come together with the member still clear of the tube-wall. Continued movement of the rod 6 expands the third elastic member 5 whereby the tube end is radially outwardly expanded into intimate engagement with the inner surface of the bore. <IMAGE>

Title: Switching transistor over-voltage protection
IPC: H02M3/337
Filed: 1979-10-09
Abstract: In a transistor inverter in which at least two normally alternatively operable transistors are connected across an input voltage subject to over-voltage surges and transients, these are sensed by an over-voltage sensing means which temporarily inhibit normal switching of the transistors for the duration of the excursion, and switch the transistors to a non-conducting state. The inverter is thus able to assume an effective voltage rating of twice its normal rating.

Title: Improvements in expandible devices for internally gripping cores or the like
IPC: F16C13/04
Filed: 1979-10-31
Abstract: An expandible device for gripping a core carrying a web of material has jaw segments 7A, expanded by balls 2 carried by recesses 3 in a body member 1. The jaw segments have arcuate inner grooves 11A which taper in depth and co-operate with the balls upon relative rotation of the jaw segments and body member to cause the jaw segments to expand into frictional gripping contact with the core. Part rotation of the core in the opposite direction will cause the jaw segments 7A to revert to a contracted position to release the core. Resilient bands 9 or tension springs (15) Figs. 13 and 14 (not shown) retain the jaw segments and bias the jaw segments into the contracted position. Additional spring clips 19 can be located between the jaw segments to contact the core and urge the jaw segments apart when the core is partly rotated to expand the jaw segments. <IMAGE>
